I've got something very similar as a function in my ~/.zshrc, except instead of days separated by lines I start a new file for each topic. Most of my notes are write-only for a day or so but I keep the old ones around just in case I need to grep through everything (and I've saved myself doing this a few times). function notes { THIS_MONTH="$(date '+%Y-%m')" mkdir -p "$NOTES_FOLDER/$THIS_MONTH" # create folder if it doesn't exist. cd "$NOTES_FOLDER/$THIS_MONTH" if [ -z "$1" ]; then return 0 fi vim $1 cd - } Running `notes` will take you to today's directory to poke around, and `notes file.md` will open file.md in the appropriate dir.
